Insulated Glass – Acoustic Performance Data Tables

STC ratings are a way to measure and compare how much sound is stopped / absorbed by any given product / material. STC ratings are used for windows, wall assemblies, doors and some constituent materials.

The STC rating is the average amount of noise stopped at 18 different frequencies, measured in decibels. STC ratings are a logarithmic scale similar to the earthquake Richter Scale, which means each escalating number is significantly higher in performance than the previous number. It is a non-linear scale.

Aside from routine HVAC maintenance, entryway systems also affect how efficiently the air conditioning in a building distributes throughout the space. In a 2006 MIT study, revolving doors were proven to […]

Calculating Wind Loads on Buildings

When structural engineers and architects collaborate during the design phase for buildings or structures, one of the most important factors requiring consideration is the velocity and imposed load of wind on the building and the constituent components (such as doors and windows). When calculating these loads, there are several factors that need to be considered. Some of these factors are not as intuitive as one might think.

Automatic Door Maintenance

If you have automatic doors installed at your building, whether commercial or residential, it is important that you plan their maintenance carefully in order to keep them functional for a long time. If you don’t take measures to maintain your automatic doors, they can end up damaged before they have reached their full design service life. Depending upon factors such as the amount of traffic and the age of doors, you can select anything from a basic to an all-inclusive full maintenance program type that your local door service company has to offer.

It is often times difficult to get a “500 mile high” view of trends in the automatic door community. It is a community of regional distribution channels and considerations. In 2004, AAADM (The American Association of Automatic Door Manufacturer’s – www.aaadm.com) conducted an influential study / survey which helped to fill in the blanks in […]
